Washington, D.C.-– Researchers at the Carnegie Institution have discovered a new efficient way to pump heat using crystals. The crystals can pump or extract heat, even on the nanoscale, so they could be used on computer chips to prevent overheating or even meltdown, which is currently a major limit to higher computer speeds. The research is published in the Physical Review Letters. (more…)
UD doctoral student studies ways to improve lithium battery performance
Lithium batteries are used in many devices such as cell phones, computers and cameras, among others.
University of Delaware doctoral student Wei-Fan Kuan is investigating ways to improve membranes used in lithium batteries by capitalizing on the innate properties of block copolymers.
It is work that he believes will become increasingly important as the components in electronic devices continue to get smaller. (more…)
MU researcher finds that prostate tumor cells are more susceptible to treatment after being exposed to resveratrol, a compound found in grape skins and red wine.
Resveratrol, a compound found commonly in grape skins and red wine, has been shown to have several beneficial effects on human health, including cardiovascular health and stroke prevention. Now, a University of Missouri researcher has discovered that the compound can make prostate tumor cells more susceptible to radiation treatment, increasing the chances of a full recovery from all types of prostate cancer, including aggressive tumors.
“Other studies have noted that resveratrol made tumor cells more susceptible to chemotherapy, and we wanted to see if it had the same effect for radiation therapy,” said Michael Nicholl, an assistant professor of surgical oncology in the MU School of Medicine. “We found that when exposed to the compound, the tumor cells were more susceptible to radiation treatment, but that the effect was greater than just treating with both compounds separately.” (more…)
New software and services enable businesses to create and enhance mobile strategies
ARMONK, N.Y. – 09 Nov 2012: IBM today unveiled a suite of new software and services that enables global organizations to build a comprehensive mobile computing strategy – from securing and managing devices, to creating mobile applications and analyzing data. These new offerings are part of a move by IBM to capitalize on the growing market opportunity for mobile that is expected to drive $130B in revenue for the IT industry by 2015, according to a recent study.[i]
As organizations increasingly view mobile computing as the next platform to conduct business, the market is evolving beyond just the device. Business leaders including the chief information officers (CIOs) and increasingly chief marketing officers (CMOs) of global organizations such as airlines, retailers, governments and healthcare providers are among the businesses turning to IBM to ensure mobile services and solutions are readily available to constituents and in full compliance with IT strategies. They need solutions that can be applied across any mobile environment and device — whether a laptop, smartphone or tablet — and can provide an underlying IT infrastructure that is always available, secure, effectively manages data, and integrates both front and back-end systems.

Berkeley Lab Finding that Protein Folding Funnels Also Apply to Self-Assembly Should Benefit Biomimicry and Nanosynthesis
Proteins are able to self-assemble into a wide range of highly ordered structures that feature a diverse array of properties. Through biomimicry – technological innovation inspired by nature – humans hope to emulate proteins and produce our own version of self-assembling molecules. A key to accomplishing this is understanding how protein-folding – a process critical to the form and function of a protein – is extended from individual proteins to complex assemblies. (more…)
COLLEGE PARK, Md – The size of a CEO’s signature can reveal a lot about that leader and company success. A large, embellished signature signals a heavy narcissist and diminished firm performance, concludes a study of 400 CEO signatures by researchers in the University of Maryland’s Robert H. Smith School of Business. (more…)
A Yale-led scientific team has produced the most comprehensive family tree for birds to date, connecting all living bird species — nearly 10,000 in total — and revealing surprising new details about their evolutionary history and its geographic context.
Analysis of the family tree shows when and where birds diversified — and that birds’ diversification rate has increased over the last 50 million years, challenging the conventional wisdom of biodiversity experts.
“It’s the first time that we have — for such a large group of species and with such a high degree of confidence — the full global picture of diversification in time and space,” said biologist Walter Jetz of Yale, lead author of the team’s research paper, published Oct. 31 online in the journal Nature.
